Description

Technical Field

[0001] The present invention relates to the field of aerial work machinery, and in particular to a pipeline guiding mechanism and aerial work equipment. Background Art

[0002] The equipment used for maintenance operations such as aircraft de-icing is generally for aerial work. The aerial work vehicle mainly includes a vehicle chassis, a slewing mechanism, a turntable, a boom, a luffing mechanism and a working bucket. The boom includes a main boom and a flying boom connected to the end of the main boom. The luffing mechanism includes a main luffing mechanism and a flying boom luffing mechanism. The slewing mechanism is installed on the vehicle chassis, the turntable is installed on the slewing mechanism, and the boom is installed on the turntable. The main luffing mechanism is installed between the turntable and the main boom to change the pitch angle of the main boom. The flying boom luffing mechanism is installed between the main boom and the flying boom to change the pitch angle of the flying boom. The working bucket is installed at the end of the flying boom. When driving, the boom is folded to the top of the aerial work vehicle.

[0003] Typically, the control system on the bucket is connected to the vehicle's electrical control box via wires. The boom's luffing mechanism is connected to the vehicle's hydraulic oil tank via hydraulic lines. The spray guns used for cleaning and de-icing in the bucket also need to be connected to the vehicle's water tank, de-icing fluid tank, and other systems via water pipes. To prevent these lines from twisting due to the boom's rotation during aerial work platform slewing operations, a center swivel joint is typically required to connect the wires, hydraulic lines, and water pipes from the vehicle to the boom.

[0004] To facilitate air transportation, the inventor has designed a relatively small aerial work equipment for aircraft de-icing (not yet disclosed). However, because the aerial work equipment is relatively small in overall size, compact in structure, and inconvenient to install a center swivel joint, a new device is needed to replace the center swivel joint. Summary of the Invention

DETAILED DESCRIPTION

[0039] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] In the description of the present invention, the directions or positions of "upper" and "lower" are based on the Figure 1 and attached Figure 3 The orientation or position relationship shown, where "looking down" is Figure 1 The downward direction of "vertical" is Figure 3 It should be understood that these directional terms are only used to facilitate the description of the present invention and simplify the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention.

[0041] Example 1

[0042] The first embodiment of the present invention provides a pipeline guiding mechanism. Figure 1 and Figure 2 As shown, the pipeline guide mechanism 100 includes a guide bracket 1 and a pipeline bracket 2. The guide bracket 1 is formed with a mounting portion 1a and a guide surface, and the pipeline bracket 2 is formed with a pipeline channel 2a. The pipeline channel 2a can be used for pipelines that need to be guided, such as the pipeline 600 of the aerial work equipment (refer to FIG. Figure 4 ) passing through it. The pipeline support 2 is located on the side of the guide bracket 1 away from the mounting portion 1a and can rotate synchronously with the guide bracket 1. When the pipeline support 2 and the guide bracket 1 rotate synchronously, the pipeline support 2 can guide the pipeline 600 passing through the pipeline channel 2a along the guide surface of the guide bracket 1 and move synchronously with the guide bracket 1.

[0043] That is, when the guide bracket 1 rotates clockwise or counterclockwise from the initial position, the pipeline support 2 can guide the pipeline 600 passing through the pipeline channel 2a to be wound around the guide surface of the guide bracket 1. When the pipeline support 2 rotated to the initial position by reverse rotation, the pipeline support 2 can guide the pipeline 600 passing through the pipeline channel 2a to be unwound along the guide surface of the guide bracket 1, thereby preventing the pipeline 600 from being wound around the telescopic arm 400 (refer to FIG. Figure 4 ) and other mechanisms during synchronous rotation.

[0044] Compared with common center rotary joints, the pipeline guide mechanism 100 has a simple structure, low cost and occupies less installation space. Therefore, the pipeline guide mechanism 100 can be applied to equipment with relatively compact structure and inconvenient installation of center rotary joints.

[0045] In this embodiment, the pipeline guide mechanism 100 also includes a connecting plate 3, one end of the connecting plate 3 is connected to the guide bracket 1, and the other end of the connecting plate 3 is connected to the pipeline bracket 2. That is, the pipeline bracket 2 is connected to the guide bracket 1 through the connecting plate 3 to form a whole. When the guide bracket 1 rotates, the pipeline bracket 2 can rotate together with the guide bracket 1, thereby realizing the synchronous rotation of the pipeline bracket 2 and the guide bracket 1.

[0046] It should be noted that there are many ways to realize the rotation of the guide bracket 1, for example, Figure 4Taking the pipeline guide mechanism 100 shown in the figure as an example, the guide mechanism 100 actually rotates synchronously with the telescopic boom 400. Therefore, the guide bracket 1 can be connected to the telescopic boom 400, and when the telescopic boom 400 rotates, it can drive the guide bracket 1 to rotate together. The guide bracket 1 can also be directly connected to the slewing mechanism 300 of the aerial work equipment instead of the telescopic boom 400, and when the slewing mechanism 300 rotates, it can drive the guide bracket 1 to rotate together. Accordingly, in other embodiments, the pipeline guide mechanism 100 can also be provided without a connecting plate 3, and the pipeline bracket 2 can be directly connected to the guide bracket 1. Alternatively, the pipeline bracket 2 can also be connected to the guide bracket 1 instead of forming an integral whole. For example, the pipeline bracket 2 and the guide bracket 1 can be connected to the telescopic boom 400 or the slewing mechanism 300 respectively, or one of the pipeline bracket 2 and the guide bracket 1 can be connected to the telescopic boom 400 and the other can be connected to the slewing mechanism 300, as long as the pipeline bracket 2 and the guide bracket 1 can rotate synchronously.

[0047] Furthermore, the guide bracket 1 of this embodiment includes a guide member 11 and a first mounting plate 12 having a mounting hole, the guide surface is formed on the guide member 11, and the mounting hole allows the telescopic arm 400 to pass through it, so that the guide bracket 1 can be set on the periphery of the telescopic arm 400, thereby realizing the synchronous rotation of the guide bracket 1 and the telescopic arm 400.

[0048] In other words, the mounting hole here is the mounting portion 1a formed on the guide bracket 1. The guide member 11 is disposed on the first mounting plate 12 and is located outside the mounting hole. When the pipeline bracket 2 and the guide bracket 1 rotate synchronously, the pipeline bracket 2 can guide the pipeline 600 passing through the pipeline channel 2a along the guide surface of the guide member 11 to move synchronously with the guide bracket 1. The purpose of providing the first mounting plate 12 is to facilitate the installation of the guide member 11. In other embodiments, the first mounting plate 12 may not be provided. For example, the guide member 11 can be directly connected to the slewing mechanism 300.

[0049] Furthermore, since the guide bracket 1 of this embodiment is connected to the telescopic arm 400, in order to ensure that the guide bracket 1 can be firmly installed, the guide bracket 1 of this embodiment is provided with two first mounting plates 12, and the two first mounting plates 12 are arranged opposite to each other. At the same time, in order to save installation space and avoid interference between the guide member 11 and other components on the aerial work equipment, the guide member 11 of this embodiment includes a plurality of guide rods 111, and the plurality of guide rods 111 are arranged at intervals between the two first mounting plates 12 and located on the periphery of the mounting hole. The outer peripheral surface formed by the plurality of guide rods 111 is the guide surface. When the pipeline bracket 2 and the guide bracket 1 rotate synchronously, the pipeline bracket 2 can guide the pipeline 600 passing through the pipeline channel 2a to move synchronously with the guide bracket 1 along the outer peripheral surface formed by the plurality of guide rods 111.

[0050] The first mounting plate 12 of this embodiment protrudes outward along the periphery of the mounting hole to form a plurality of protrusions 12a for securing the guide rod 111. An accommodating space 12b is formed between two adjacent protrusions 12a. The accommodating space 12b facilitates the placement of a hydraulic cylinder for use with the telescopic boom 400 on the periphery of the telescopic boom 400. In other embodiments, only one first mounting plate 12 may be provided, with one end of the guide rod 111 connected to the slewing mechanism 300 and the other end connected to the first mounting plate 12. In other embodiments, the guide rod 111 may not be provided. For example, the guide member 11 may be an annular plate surrounding the periphery of the mounting hole, or the guide member 11 may be a plurality of arc-shaped plates spaced apart around the periphery of the mounting hole.

[0051] Furthermore, the guide rod 111 of this embodiment is rotatably connected to the first mounting plate 12. When the pipeline support 2 guides the pipeline 600 passing through the pipeline channel 2a to move synchronously with the guide support 1 along the guide surface of the guide support 1, the guide rod 111 can not only guide the movement of the pipeline 600 through its own rotation, but also reduce the resistance between the guide rod 111 and the pipeline 600, thereby making the movement process of the pipeline 600 smoother and faster.

[0052] Furthermore, the pipeline support 2 of this embodiment includes a second mounting plate 22 and a guide rod 21 arranged on the second mounting plate 22. The number of guide rods 21 is at least two, and at least two guide rods 21 are arranged at intervals. A pipeline channel 2a is formed between two adjacent guide rods 21. When the pipeline support 2 and the guide support 1 rotate synchronously, the pipeline support 2 guides the pipeline 600 passing through the pipeline channel 2a along the guide surface of the guide support 1 through the guide rod 21, and moves synchronously with the guide support 1.

[0053] The purpose of setting the guide rod 21 is that, on the one hand, after the pipeline 600 passes through the pipeline channel 2a, the two adjacent guide rods 21 can limit the pipeline 600; on the other hand, when the pipeline support 2 and the guide support 1 rotate synchronously, the guide rod 21 can drive the pipeline 600 to move together, thereby guiding the pipeline 600.

[0054] It should be noted that the pipeline guide mechanism 100 of this embodiment is provided with two pipeline supports 2. For the convenience of description, one of the pipeline supports 2 is called the electric-hydraulic pipe support 2c, and the other is called the water pipe support 2b. Three guide rods 21 are provided on the electric-hydraulic pipe support 2c. Two pipeline channels 2a are formed between the three guide rods 21. The electric-hydraulic pipe support 2c is mainly used to guide the electric wire 600c and the hydraulic pipe 600b at the same time (refer to Figure 4) These two types of pipelines, and the water pipe bracket 2b is only provided with two guide rods 21, and a pipeline channel 2a is formed between the two guide rods 21. The water pipe bracket 2b is mainly used to guide the water pipe 600a (reference Figure 4 )This type of pipeline.

[0055] It is understood that in actual use, the number of guide rods 21 in a single pipeline support 2 can be adjusted based on needs, such as the number and / or type of pipelines 600. However, at least two guide rods 21 are required. The number of pipelines 600 passing through a single pipeline passage 2a can be one or more. Furthermore, the number of pipeline supports 2 is not limited to two; only one pipeline support 2 or more pipeline supports 2 can be provided as needed.

[0056] The guide rod 21 of this embodiment is disposed between the two second mounting plates 22, thereby facilitating the fixing of the guide rod 21 and preventing the pipeline 600 from slipping out of the pipeline passage 2a. It is understood that in other embodiments, only one second mounting plate 22 may be provided. In other embodiments, the guide rod 21 may not be provided. For example, the guide rod 21 may be replaced with a baffle, or a guide plate may be provided on the second mounting plate 22, with one or multiple slots provided on the guide plate at intervals, the slots being equivalent to the pipeline passage 2a. Alternatively, the pipeline support 2 may be directly replaced with channel steel, curved plates, or the like. As long as the pipeline support 2 and the guide support 1 rotate synchronously, the pipeline support 2 can guide the pipeline 600 passing through the pipeline passage 2a along the guide surface of the guide support 1 to move synchronously with the guide support 1.

[0057] Furthermore, the guide rod 21 of this embodiment is rotatably connected to the second mounting plate 22, thereby reducing the resistance between the guide rod 21 and the pipeline when the pipeline 600 moves in the pipeline channel 2a, thereby making the movement of the pipeline 600 more flexible.

[0058] It should be noted that the pipeline guide mechanism 100 of this embodiment is not limited to use on aerial work equipment. The pipeline guide mechanism 100 can also be used to replace the central rotary joint on other equipment with rotational movement, such as cranes, to ensure that the pipeline connected from the relatively stationary lower component to the rotating upper component will not be twisted during the rotational movement.

[0059] Example 2

[0060] The second embodiment of the present invention provides an aerial work equipment, such as Figure 3 and Figure 4 As shown, the aerial work equipment includes a vehicle body 200, a rotary mechanism 300 (refer to Figure 5), a telescopic boom 400 with at least two interconnected boom sections 4, a winding drum 500, a pipeline 600, and a pipeline guide mechanism 100 provided in the first embodiment; a slewing mechanism 300 is rotatably connected to the vehicle body 200, and the telescopic boom 400 is rotatably connected to the vehicle body 200, with the telescopic boom 400 extending and retracting in the vertical direction; the pipeline guide mechanism 100 can rotate synchronously with the telescopic boom 400; the winding drum 500 is connected to the telescopic boom 400, and the telescopic boom 400 can drive the winding drum 500 to move in the vertical direction by extending and retracting; the pipeline 600 is wound around the winding drum 500, and one end of the pipeline 600 passes through the pipeline channel 2a and is fixedly connected to the vehicle body 200. In other words, the telescopic boom 400 of this embodiment can be extended and retracted in the vertical direction and can also rotate relative to the vehicle body 200 via the slewing mechanism 300.

[0061] Since the pipeline guide mechanism is arranged on the outside of the telescopic arm, the installation and maintenance of the pipeline guide mechanism and the pipeline are convenient. It can replace the central swivel joint to prevent the pipeline from twisting during the rotation of the telescopic arm, while reducing manufacturing and maintenance costs.

[0062] Furthermore, the guide bracket 1 of this embodiment is connected to the outermost boom section 4 of the telescopic boom 400 via the mounting portion 1a, thereby enabling the telescopic boom 400 to rotate synchronously with the guide bracket 1. To ensure a secure installation of the pipeline support 2, the connecting plate 3 is simultaneously connected to the guide bracket 1, the pipeline support 2, and the outermost boom section 4 of the telescopic boom 400.

[0063] Furthermore, the aerial work equipment of this embodiment is an aircraft maintenance vehicle, which also includes a flying boom 700 and a boom cylinder 800; the flying boom 700 is pivotally connected to the innermost arm section 4 in the telescopic boom 400, and the two ends of the boom cylinder 800 are respectively connected to the flying boom 700 and the innermost arm section 4. The boom cylinder 800 is mainly used to adjust the amplitude of the flying boom 700 to adapt to different working heights.

[0064] The aircraft maintenance vehicle of this embodiment is mainly used for cleaning, de-icing and maintenance of aircraft. Therefore, a work basket 900 for operation is also provided at the end of the flying arm 700 away from the innermost arm section 4, and a control system (not shown) is provided in the work basket 900.

[0065] Correspondingly, three reels 500 are provided on the telescopic boom 400 of this embodiment. For the convenience of description, the three reels 500 are respectively referred to as the water pipe reel 500a, the oil pipe reel 500b and the electric wire reel 500c. The water pipe reel 500a, the oil pipe reel 500b and the electric wire reel 500c are respectively fixedly connected to the innermost arm section 4 of the telescopic boom 400. For the convenience of description, the pipelines 600 on the three reels 500 are respectively referred to as the water pipe 600a, the hydraulic pipe 600b and the electric wire 600c. The water pipe 600a, the hydraulic pipe 600b and the electric wire 600c are respectively connected to the water pipe reel 500a, the oil pipe reel 500b and the electric wire reel 500c. In one-to-one correspondence, a pipeline channel 2a is formed on the pipeline bracket 2b, and two pipeline channels 2a are formed on the electro-hydraulic pipe bracket 2c. The water pipe 600a is wound around the water pipe winding drum 500a, and one end of the water pipe 600a passes through the pipeline channel 2a on the water pipe bracket 2b and is fixedly connected to the vehicle body 200. The hydraulic pipe 600b is wound around the oil pipe winding drum 500b, and one end of the hydraulic pipe 600b passes through a pipeline channel 2a on the electro-hydraulic pipe bracket 2c and is fixedly connected to the vehicle body 200. The electric wire 600c is wound around the electric wire winding drum 500c, and one end of the electric wire 600c passes through the other pipeline channel 2a on the electro-hydraulic pipe bracket 2c and is fixedly connected to the vehicle body 200.

[0066] The vehicle body 200 of this embodiment includes a water tank (not shown), a detergent tank (not shown), an anti-icing liquid tank (not shown), and a de-icing liquid tank (not shown). The water tank, detergent tank, anti-icing liquid tank, and de-icing liquid tank respectively store liquids such as water, detergent, anti-icing liquid, and de-icing liquid. There are two water pipes 600a, and the two water pipes 600a pass through the pipeline channel 2a on the water pipe bracket 2b at the same time. One end of the first water pipe 600a is connected to the water tank and the de-icing liquid tank, and the other end of the first water pipe 600a is provided with a first spray gun (not shown). One end of the second water pipe 600a is connected to the detergent tank and the anti-icing liquid tank, and the other end of the second water pipe 600a is provided with a second spray gun (not shown). The first spray gun and the second spray gun are used in conjunction to facilitate cleaning or de-icing operations on the aircraft. It should be noted that, in actual use, the de-icing liquid tank and the water tank may share one liquid storage tank, and the anti-icing liquid tank and the cleaning agent tank may share another liquid storage tank. When in use, de-icing liquid or water is stored in one liquid storage tank as needed, and anti-icing liquid or cleaning agent is stored in another liquid storage tank. One end of the first water pipe 600a is connected to one liquid storage tank, and one end of the second water pipe 600a is connected to the other liquid storage tank.

[0067] The vehicle body 200 of this embodiment also includes a hydraulic oil tank (not shown), and there are also two hydraulic pipes 600b, one is an oil inlet pipe and the other is an oil outlet pipe. The two hydraulic pipes 600b pass through a pipeline channel 2a on the electro-hydraulic pipe bracket 2c at the same time. One end of the two hydraulic pipes 600b is respectively connected to the hydraulic oil tank, and the other end of the two hydraulic pipes 600b is respectively connected to the boom cylinder 800.

[0068] The vehicle body 200 of this embodiment also includes an electrical control box (not shown). Two electrical wires 600c are also present. Both wires 600c pass through another pipeline channel 2a on the hydraulic pipe support 2c. One end of each wire 600c is connected to the electrical control box, while the other end of each wire 600c is connected to the control system in the work basket 900. Sharing a single hydraulic pipe support 2c for the hydraulic pipe 600b and electrical wires 600c has the advantage of reducing the number of pipe supports 2 used and allowing for a more compact arrangement of the oil pipe reel 500b and electrical wire reel 500c.

[0069] In addition, in this embodiment, the diameter of the water pipe reel 500a is almost twice the diameter of the oil pipe reel 500b and three times the diameter of the wire reel 500c. The water pipe reel 500a requires more installation space, and the aperture of the water pipe 600a is also the largest compared to the wire 600c and the hydraulic pipe 600b. Therefore, in order to make the water pipe reel 500a, the oil pipe reel 500b and the wire reel 500c more compact, in this embodiment, the oil pipe reel 500b and the wire reel 500c are arranged on the same side of the telescopic arm 400, and the water pipe reel 500a is arranged on the side of the telescopic arm 400 away from the oil pipe reel 500b and the wire reel 500c.

[0070] The electric-hydraulic pipe bracket 2c and the water pipe bracket 2b are symmetrically arranged along the rotation center of the guide bracket 1, which is equivalent to that after the guide bracket 1 rotates 180° clockwise or counterclockwise along the rotation center, the electric-hydraulic pipe bracket 2c can move to the position where the water pipe bracket 2b is located before the guide bracket 1 rotates, and the water pipe bracket 2b can move to the position where the electric-hydraulic pipe bracket 2c is located before the guide bracket 1 rotates, thereby avoiding interference between the water pipe 600a and the electric wire 600c and the hydraulic pipe 600b during movement.

[0071] Taking the water pipe 600a as an example, the following briefly describes the winding process of the water pipe 600a on the guide bracket 1:

[0072] like Figures 3 to 5As shown, in the initial state, the telescopic arm 400 is in a retracted state. When the telescopic arm 400 is extended in the vertical direction, the water pipe winding disk 500a continuously releases the line by rotating. When the telescopic arm 400 is extended to a suitable height, the water pipe winding disk 500a stops rotating. At this time, the telescopic arm 400 may need to be rotated according to the working conditions. The telescopic arm 400 of this embodiment can be rotated 150° clockwise or 150° counterclockwise. When rotating counterclockwise or clockwise, the winding method of the pipeline 600 on the guide bracket 1 is exactly the same. Figure 6 Taking the counterclockwise rotation of the telescopic arm 400 as an example, when the telescopic arm 400 rotates counterclockwise, the water pipe bracket 2b drives the water pipe 600a to move together, and at the same time, the water pipe winding disc 500a continues to pay out the line by rotating. In actual use, a driving device such as a rotary motor can be set on the water pipe winding disc 500a, and the rotary motor drives the water pipe winding disc 500a to rotate and pay out the line, so that the water pipe 600a can be wound around the outer peripheral surface of multiple guide rods 111. Similarly, when the telescopic arm 400 that has been rotated into place needs to return to its initial position before the rotation, the water pipe bracket 2b can also guide the water pipe 600a to move together in the opposite direction. At the same time, the water pipe winding disc 500a can also be driven by a driving device such as a rotary motor to rotate in the opposite direction to reel in the line. When the telescopic arm 400 returns to its initial position, the water pipe 600a detaches from the guide rod 111 and returns to the position before it was wound around the guide bracket 1, that is, Figure 5 The status shown.

[0073] The winding method for the hydraulic pipe 600b and the electrical wire 600c on the guide bracket 1 is identical to that for the water pipe 600a and will not be further described here. Furthermore, because the hydraulic pipe bracket 2c and the water pipe bracket 2b are symmetrically arranged about the rotation center of the guide bracket 1, and the telescopic boom 400 of this embodiment rotates within a range of ±150°, the water pipe 600a, hydraulic pipe 600b, and electrical wire 600c will not become entangled, thereby affecting the normal rotation of the telescopic boom 400, regardless of whether the telescopic boom 400 rotates counterclockwise or clockwise.

[0074] In order to adapt to air transportation, the structure of the aircraft maintenance vehicle of this embodiment must be as compact as possible. Since the pipeline guide mechanism 100 has a simple structure and occupies less installation space, when the pipeline guide mechanism 100 is used to replace the central rotary joint, it can avoid the possible distortion of the pipeline 600 during the synchronous rotation with the telescopic arm 400 while also saving installation space.

[0075] Each of the above embodiments provides a pipeline guide mechanism and aerial work equipment. By providing the pipeline guide mechanism, the pipeline support can be used to guide the pipeline along the guide surface of the guide support during rotation of the telescopic boom, thereby preventing the pipeline from twisting during rotation with the telescopic boom. Furthermore, due to the simple structure of the pipeline guide mechanism and the limited installation space it occupies, once the overall size of the aerial work equipment is reduced to a size suitable for air transport, the pipeline guide mechanism can be used to replace the central swivel joint, thereby resolving the problem of the central swivel joint being unable to be installed due to limited installation space.

[0076] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
